PURPOSE:To obtain a rotary leg mechanism having high traveling performance through unleveled land by supporting a plurality of rotary legs rollably on the outer circumference of a radial wheel rotatable through a chain, and coupling respective rotary legs to an eccentric ring having adjustable eccentricity through telescopic members. CONSTITUTION:Many rotary legs 3 having curved treads 31 are supported rotatably on horizontal shafts 2 at the outer ends of a radial wheel 1, where respective rotary legs 3 are coupled to an eccentric ring through pins. The eccentric ring 5 is fixed to the wheel 1 with rotation thereof being stopped by means of a holding piece 52 and a holding cam 53. A maneuvering section 6 is provided in the center of the eccentric ring 5 and displaced through reciprocation of a control body 8 fastened with a screw 9 which is rotated by a motor 13 through bevel gear row 10, 11. The screw 9 is supported on a tubular shaft 20 which is freely rotated by means of a worm 21 through a worm gear 19. A chain wheel 15 is formed on the rear face of the wheel 1 so as to transmit power through a chain 16. |
